A term coined to reference the falling of a snowflake in Texas, which often is used as a signal from the heavens to indicate the approach of the apocalypse. School and buisiness will cease all over the state and everyone will take the day off to pray for mercy from the freezing wrath of being buried under snow. Often occurs in Febuary, once every hundred or so years. So far thtey've only been false signals and the world as we know it has not yet ended. There are some who consider the Texas Snowday as mere superstition and file it along with the Y2K bug and other such nonsensical theories. These people are considered too be uneducated and unintelligent.

"Dear lord, please rescue us from the everlasting darkness of te barren winter and restore the fire to our souls"
-traditional Texas Snowday Prayer, should be repeated consistently between the hours of 6 P.M. and 6 A.M. for best effects.
